sorry, didn't mean to nitpick! This just made me curious...

For the archives, it seems

  bool foo = 16 & 24;

is valid C99, because

6.5.16.1,2:
"In simple assignment (=), the value of the right operand
is converted to the type of the assignment expression…"

and

6.3.1.2:
"When any scalar value is converted to _Bool, the result is 0 if the
value compares equal to 0; otherwise, the result is 1"

Language lawyer end. :)
